Gutter filter



FIG. 1 is a perspective view of the gutter filter:

FIG. 2 is a side view thereof;

FIG. 3 is a top view thereof;

FIG. 4 is a front view thereof;

FIG. 5 is a side view thereof showing the side opposite that shown in FIG. 2;

FIG. 6 is a rear view thereof; and,

FIG. 7 is a bottom view thereof.

The broken line showing of portions of a gutter is included for the purpose of illustrating environmental detail and forms no part of the claimed design. 

I claim the ornamental design for the gutter filter, as shown and described.
